Singapore, 13 June 2017: In the process of heat exchanger or condensor cleaning, the Automatic Brush Cleaning Systems is a popular tool that helps to keep the tube walls in the top running condition.

With the continuous functioning of the equipment, there are no chances to foul during the operation with Eqobrush running. Fouling build-up reduces the working efficiency and demands for cleaning sessions with interruptions of operations. Between cleaning sessions, the heat exchange efficiency is gradually reduced up to a level where heat- dissipation becomes a bottle-neck for the production capacity of the operation.

In case, if the fouling turns to be uncontrolled then you may find unexpected shutdown of the system which involves the high expenses. However, Total Fouling Related Cost (TFRC) in the processing industry is hard to evaluate. In a study, it is found that the TFRC requires 8% of the total maintenance budget, including 5% of the energy consumed to overcome fouling. TFRC incorporates the cost of the following components:

• Cost of Cleaning
• Production Standstill During Cleaning
• Efficiency Loss Between Cleaning Intervals
• Unscheduled Interruptions

To minimize TFRC while maximizing the production with controlled operations, you need to follow the right path or technique. So, to avail the benefits, keep the heat exchanger tubes clean at all times.

In conventional systems, the TFRC are the sum of the cleaning cost and the efficiency losses and depending on the specific situation the minimum is to be established from experience.

This example (for a 250 RT chiller [150 kWh] with cleaning cost at US$ 3000 per session [US$ 2 per tube] and energy cost of US$ 0.10 per kWh and a US$ 30,000 investment on a brushing system depreciated over 15 years) shows a 90% reduction of TFRC from US$ 20,000 to US$ 2,000 annually.

Eqobrush, the best Automatic Tube Cleaning System supports the heat exchangers to perform effectively and keep TFRC close to zero with no surprising factors ahead. Not only this, there are other additional benefits of introducing Eqobrush such as reduction of water consumption in the cooling tower and energy saving options in condenser cooling via VFD controlled cooling tower fan.

Nowadays, the impact on CAPEX (capital expenditure) is also considered as an another essential economic benefit of Automatic Tube Cleaning. The industrial design engineers of heat exchangers are well aware of the fact of constant fouling build-up and the loss of efficiency of heat exchange. Therefore, these exchangers are designed with surplus heat exchange surface, near about 30%. Eliminating over design will greatly impact the CAPEX of this equipment and the associated installation cost.

Considering all the factors, Watco-Group, the leading company manufacturers Eqobrush to managing the functioning of the heat exchanger in top condition. It is superbly designed for offering high frequency tube brushing, i.e. 6 or more cleanings per day. It has smart design tube inserts and requires no additional energy.
